tracing: Fix logged instance name on creation failure

Browse source

When boot instance creation fails, the kernel incorrectly logs "(null)"
as the instance name because strsep() consumes curr_str entirely during
parsing.

Print the properly parsed name variable instead. And while at it log
the error code.
